Understanding the Evolution of the Early Solar System through Paleomagnetism of Meteorites

Abstract
Magnetic records from meteorites and their components can provide important information about the evolution and architecture of the early solar system. That is because large-scale magnetic fields and gas are coupled in protoplanetary disks. In this talk, I will present how we can use micro-paleomagnetism to obtain magnetic records from 100 µm-sized meteoritic inclusions (i.e., calcium-aluminum-rich inclusions and chondrules) to obtain constraints on the evolution of the early solar system. I will discuss how (1) the magnetic records from calcium-aluminum-rich inclusions point to the presence of magnetized disk winds and/or stellar outbursts during the very beginning of the solar system and (2) the magnetic records from chondrules suggest the presence of a disk substructure a few million years later. These results provide information about mechanisms that drove mass and angular momentum during the protoplanetary disk phase of the solar system, and how chemical reservoirs were kept apart during that time. In turn, learning how our solar system evolved can help us understand how planetary systems form elsewhere.
